Printing fluid cartridge having cartridge body and bracket

Abstract

In a printing fluid cartridge, a cartridge body has a printing fluid delivery unit provided on a first cartridge-body surface. A bracket has at least a first bracket wall confronting the first cartridge-body surface, and a second bracket wall extending continuously from the first bracket wall in a first direction. The bracket is capable of moving relative to the cartridge body in a direction along which the second bracket wall contacts and separates from the cartridge body. A restriction member is configured to be detachably mounted on the cartridge body and the bracket, and is configured to, when the restriction member is mounted on the cartridge body and the bracket, restrict relative movement between the cartridge body and the bracket, with the second bracket wall of the bracket in contact with the cartridge body.

What is claimed is: 
     
       1. A printing fluid cartridge, comprising:
 a cartridge body having a printing fluid delivery unit provided on a first cartridge-body surface, the printing fluid delivery unit extending in a first direction; 
 a bracket having at least a first bracket wall that confronts the first cartridge-body surface of the cartridge body, and a second bracket wall extending continuously from the first bracket wall in the first direction, the bracket being capable of moving relative to the cartridge body in a second direction along which the second bracket wall contacts and separates from the cartridge body, the second direction intersecting the first direction; and 
 a restriction member that is configured to be detachably mounted on the cartridge body and the bracket, the restriction member being configured to, when the restriction member is mounted on the cartridge body and the bracket, restrict relative movement between the cartridge body and the bracket in the second direction and maintain contact between the second bracket wall of the bracket and the cartridge body, 
 wherein an electrical interface is provided on the second bracket wall of the bracket, and 
 wherein the restriction member includes a hook configured to urge the cartridge body in a direction toward the electrical interface, thereby restricting relative movement between the cartridge body and the bracket in the second direction. 
 
     
     
       2. The printing fluid cartridge according to  claim 1 , wherein the hook is configured to engage with the cartridge body, and wherein the restriction member further includes:
 an engaging part configured to engage with the bracket, 
 wherein the hook and the engaging part are configured so as to be engaged with the cartridge body and the bracket, respectively, while being aligned in the second direction. 
 
     
     
       3. The printing fluid cartridge according to  claim 2 , wherein the hook is elastically deformable and urges the cartridge body in a direction for placing the second bracket wall in contact with the cartridge body when the restriction member is mounted on the cartridge body and the bracket. 
     
     
       4. The printing fluid cartridge according to  claim 2 , wherein
 the cartridge body has an air communicating part provided on the first cartridge-body surface, 
 the bracket is formed with a first opening allowing the printing fluid delivery unit to protrude outwardly and a second opening exposing the air communicating part outwardly, the first opening and the second opening being positioned on the first bracket wall, 
 the hook is engaged with the printing fluid delivery unit on the cartridge body, 
 the engaging part is engaged with the bracket at a periphery of the second opening. 
 
     
     
       5. The printing fluid cartridge according to  claim 4 , wherein the restriction member includes a release part that is configured to open a sealing part that is configured to seal the air communicating part, the release part being configured to open the sealing part by moving in a direction toward the sealing part. 
     
     
       6. The printing fluid cartridge according to  claim 4 , wherein the engaging part includes a pair of hooks that are configured to be engaged with an inner periphery of the second opening, the pair of hooks being aligned in a direction intersecting the second direction. 
     
     
       7. A restriction member capable of being mounted in a printing fluid cartridge, the printing fluid cartridge including: a cartridge body having a printing fluid delivery unit provided on a first cartridge-body surface; and a bracket having at least a first bracket wall that confronts the first cartridge-body surface of the cartridge body, and a second bracket wall extending continuously from the first bracket wall in a first direction, the printing fluid delivery unit extending in the first direction, the bracket being capable of moving relative to the cartridge body in a second direction along which the second bracket wall contacts and separates from the cartridge body, the second direction intersecting the first direction,
 the restriction member being configured to be detachably mounted on the cartridge body and the bracket, the restriction member being configured to, when the restriction member is mounted on the cartridge body and the bracket, restrict relative movement between the cartridge body and the bracket in the second direction and maintain contact between the second bracket wall of the bracket and the cartridge body, 
 wherein an electrical interface is provided on the second bracket wall of the bracket, and 
 wherein the restriction member includes a hook configured to urge the cartridge body in a direction toward the electrical interface, thereby restricting relative movement between the cartridge body and the bracket in the second direction. 
 
     
     
       8. The restriction member according to  claim 7 , wherein the hook is configured to engage with the cartridge body, and wherein the restriction member further includes:
 an engaging part configured to engage with the bracket, 
 wherein the hook and the engaging part are configured so as to be engaged with the cartridge body and the bracket, respectively, while being aligned in the second direction.
